Rumā was the wife of Sugrīva. She is mentioned in Book IV (Kishkindha Kanda) of Ramayana. Ruma was taken away from Sugrīva by Vāli following the strife of two royal Vānara brothers. Later, the fact of Rumā being withheld by Vāli became the primary justification of Rama's slaying Vāli and helping Sugrīva to become the sovereign of Kishkindha. When accused by Vāli of lowly, treacherous and unexpected assassination from the shades by Rama's arrow, Rāma says his assassination was a just punishment for the sin Vāli committed when he robbed Sugrīva of Rumā, his legally wedded spouse, and used her for his own pleasure.
